10. D-Link DCH-S160

REVIEW

DETAILS

SPECS

The D-Link DCH-S160 is part of a line of WiFi-connected home monitoring devices that keep your property safe in a number of ways. It uses a moisture-sensing wire to detect leaks, but it's somewhat limited in that it must always be plugged into an A/C power outlet.

9. Proteus WiFi

REVIEW

DETAILS

SPECS

The Proteus WiFi is a highly reliable choice that uses an A/C outlet and talks directly to your home's or business's wireless router. Just plug it into the wall and run the extra-long 5-foot sensor cable to the area you'd like to monitor.

8. Honeywell Lyric

REVIEW

DETAILS

SPECS

If simple leak detection is your main goal, take a look at the Honeywell Lyric, a specialized option from a home security giant. It often doesn't play nice with a lot of other gadgets, but it also doesn't require a third-party hub, greatly simplifying installation.

7. Fibaro Flood Sensor

REVIEW

DETAILS

SPECS

The Fibaro Flood Sensor is the latest and greatest Z-Wave-compatible model, and it's updated frequently to work alongside newer smart home brands, like HomeSeer. There's an external probe available for separate purchase to keep watch on larger areas, as well.

6. Dome Home Automation

REVIEW

DETAILS

SPECS

Get affordable protection from water damage when using the Dome Home Automation alongside one of many compatible smart-home systems. It's one of the slimmest options on the market, so it fits easily in the tiniest crevices that might be susceptible to moisture.

5. Samsung SmartThings

REVIEW

DETAILS

SPECS

The Samsung SmartThings works with one of the most popular smart home systems, and most users find it very easy to set up. Simply place it near your water heater, washing machine, or other potential problem area, and receive alarms on your smartphone.

4. Iris Indoor

REVIEW

DETAILS

SPECS

Originally for use only with Lowe's proprietary hub, the Iris Indoor now supports a variety of systems, including the up-and-coming Wink and ZigBee families. It fits easily underneath sinks, toilets, or sump pumps to keep you assured of a dry and structurally sound home.

3. Aeotec Flood and Leak

REVIEW

DETAILS

SPECS

Compatible with a wide range of the newest smart families, the Aeotec Flood and Leak can detect the presence of just fractions of a millimeter of water. It can even be submerged in any water tank to alert you if the container becomes empty.

2. Zircon Leak Alert

REVIEW

DETAILS

SPECS

The Zircon Leak Alert is a standalone, battery-powered model that communicates via the cloud rather than a dedicated hub. In case it doesn't have WiFi access to send you an e-mail, it features a super-loud 105-dB alarm that's heard easily through walls and floors.

1. LeakSmart Intelligent

REVIEW

DETAILS

SPECS

The LeakSmart Intelligent is a versatile, all-in-one way to prevent property damage when you're not at home. While most models simply alert you to any issues, this one communicates directly with its automatic valve, saving the day when no-one is around.
